Besides, the failure process of concrete is analyzed, mechanisms of chloride salts accelerating ASR and gangue effectively preventing ASR are further explored by means of optical microscope and SEM-EDAX, XRD et al.

• 此外,通过光学显微镜、SEM-EDAX、XRD等微观测试手段的运用并结合宏观测试结果,分析了混凝土在ASR-氯盐腐蚀协同作用下的破坏过程,探讨了NaCl加速碱硅酸反应的原因以及煤矸石延迟碱硅酸膨胀的机理。
